Abstract--The particle swarm is an algorithm for finding optimal regions of complex search spaces through the interaction of individuals in a population of particles. Even though t...
Abstract. A long-running transaction is an interactive component of a distributed system which must be executed as if it were a single atomic action. In principle, it should not be...
We study the notion of class refinement in a concurrent object-oriented setting. Our model is based on a combination of action systems and classes. An action system describes the b...
We present a powerful and flexible method for automatically checking the secrecy of values inside components. In our framework an attacker may monitor the external communication ...
To help programmers of high-performance computing (HPC) systems avoid communication-related errors, we employ a formal process algebra, Communicating Sequential Processes (CSP), w...
